SEW-EURODRIVE R37-AQH100 Right Angle Gear Reducer

SEW‑EURODRIVE R37‑AQH100 Right Angle Gear Reducer is a compact SEW gear unit that provides a 90‑degree drive junction with a precise reduction ratio of 9.47. It belongs to the R‑series housing family, sized as R37, with a high‑strength cast‑iron housing (SAE Class 30 or equivalent) designed for rigidity in demanding service. The output shaft design includes center‑ tapped holes to ease the installation of shaft components, and the unit uses SEW’s exclusive interlocking 2‑piece seal system (bi‑helix inner seal plus outer seal) to provide multiple sealing surfaces against contaminants. For mounting flexibility, the model supports standard flange configurations including a B5 flange with centering tenon and a B14 flange with centering tenon for sizes in the R07–R87 range, along with provisions for multiple mounting orientations and a removable inspection cover. This combination of a compact right‑angle configuration, a modest reduction ratio, and proven sealing and mounting options makes the R37‑AQH100 suitable for space‑constrained drives where reliable torque reduction at a right angle is required.
